If you tuck it in your back pocket, you’d be better off getting one of the flexible designs meant for that. I’ve got six Moleskines that I kept in an appropriate pocket for a few months each (one that didn’t expose their spines to stress) and they’re all chock-full of writing and sitting on my desk waiting to be transcribed.

So it’s all how you store it. The sewn binding will hold up FOREVER, but not if it’s exposed to stress along the seams in the wrong direction. Glue bindings, however, will get finicky in Texas heat or if they’re slightly damp or if there’s any risk of bookworms, so Moleskine’s always worked for me.
